5.1 Lifecycle and phases Most existing multiagent methods usually distinguish only analysis and design phases (Deloach et al., 2001). Very few methods deal with other phases. We can find for example a deployment phase in MASSIVE or Vowels. This deployment phase takes in our particular field a great importance since it includes the hardware/software partitioning. A last and major difference between DIAMOND and other multiagent approach is, as said previously, that DIAMOND unifies the development of the hardware part and the software part. In a traditional system design, the partitioning step stands at the beginning. In fact, a hardware requirement and a software requirement are created from the system requirements. The software part of the system is built using a multiagent method and its associated lifecycle. To cover the whole lifecycle, different formalisms are required to express different things at different levels (Herlea et al., 1999), for this reason we adopt a lifecycle using four stages mixing different expressions using more or less formal paradigms and languages (agents, components, Finite State Machines, Hardware Definition Languages). The most current lifecycle used in multiagent methods is the classical cascade lifecycle. Even if some works attempt to introduce iterative cycles as Cassiopeia (W) or Gaia, the proposal of a spiral lifecycle is very original. In the definition of requirements phase, we introduce a study of the modes of running and stops to structure the global running of the system. In the generic design phase, the design allows an abstraction of the software design and the hardware design. We use components to build the agents as few multiagent methods introducing an actual componential.
